Hello, I’m looking to use an external clock to clock the i2s signal out of an Colibri iMX7 Dual 512MB | V1.1D, and into a custom codec I’m developing. Has anyone worked this out?
I’ve done it before on an A20 chip, would the process be similar? Years ago, I had to work with the 3.x kernel, have we moved beyond that yet?
Can anyone confirm if the iMX6 / iMX7 will work with an audio signal up to 768 kHz / 32 bit on i2S?
Anyone interested in consulting on this?

What kind of codec are you developing? What is your application?

Since A20 also has a Dual-Core Cortex-A7 ARM CPU, I think the process should be similar. The current kernel we are using is 4.9.x.
Can anyone confirm if the iMX6 / iMX7 will work with an audio signal up to 768 kHz / 32 bit on i2S?
What do you mean exactly with that? We are using this codec on our Colibri imx7 board. Does this help you?
Best regards, Jaski
